VERFAHREN UND VORRICHTUNG ZUR WIEDERHERSTELLUNG DER RICHTIGEN REIHENFOLGE VON ATM-ZELLEN

摘要

Method and unit for the reconstruction of the initial order of the sequence of the flow of the cells pertaining to the same virtual channel (VC) or path (VP) at the output of the ATM switching network with high priority cell control. The method is based upon the maximum delay equalization for the scheduling of the cells to transfer at the output, by using lists addressed by pointers and a shared queues approach for the management of the contentions by more cells for the same output time slot, so to obtain a significant saving of the memory space. The resequencing unit includes memories the dimensions of which depend upon the maximum number of cells being actually present in the resequencing unit.
